o Minor bugfixes: - Clear the table recording the time of the last request for each hidden service descriptor from each HS directory on SIGNAL NEWNYM. Previously, we would clear our HS descriptor cache on SIGNAL NEWNYM, but if we had previously retrieved a descriptor (or tried to) from every directory responsible for it, we would refuse to fetch it again for up to 15 minutes. Bugfix on 0.2.2.25-alpha; fixes bug 3309.
